FISS Narrative:
Diagnosis code 6 is invalid on the bill submitted. Please refer to the most current ICD-10-CM coding book for a valid diagnosis code with dates of service on the claim.

Explanation and Suggestion:

  • This reason code indicates that the sixth diagnosis code (the code on your screen at #6 among the diagnosis codes on claim page 03) for the date of service billed does not match a valid code on the FISS ICD-10-CM code file (menu option #15)
  • Check this code against the file and correct it accordingly
  • Please correct and resubmit/rekey
  • Hardcopy submitters resubmit RTP report with corrections
